SGS Tecnos, S.A. (Electrical Testing Laboratory) has been contracted by SUNGROW POWER SUPPLY CO., LTD. to perform ‘RESPONSE DURING GRID FAULTS’ testing according to FGW-TG3: Technical Guidelines for Power Generating Units and Systems. TG3 (Revision 25 Dated 01/09/2018 + Supplement 1 Dated 22/01/2019): Determination of Electrical Characteristics of Power Generating Units and Systems, Storage Systems as well for their Components in MV, HV and EHV grids.

The following standards are covered with testing of FGW-TG3 (Revision 25 Dated 01/09/2018) (): - VDE-AR-N 4110: 2018-11. Technical requirements for the connection and operation of customer installations to the medium voltage network (TAR medium voltage). - VDE-AR-N 4120: 2018-11. Technical requirements for the connection and operation of customer installations to the high voltage network (TAR high voltage).

() As stated in chapter 11.2.1 of both covered standards.

Note:

1. The above markings are the minimum requirements required by the safety standard. For t he final production samples, the additional markings which do not give rise to misunderstanding may be added.

2. Label is attached on the side surface of enclosure and visible after installation .

3. Labels of other models are as the same with SG3125HV-30’s except the parameters of rating.

Equipment under testing:

- SG3125HV-30

The variants models are:

- SG3000HV-30

- SG3400HV-30

Note: The EUT is composed of two same structure modules, only one module was tested in all tests. This corresponds with half of the rated power of the complete unit.Report N. 2221 / 0124 - 1

Attachment I Page 8 of 327 Rev. 0 FRT test in FGW-TG3+SP1: Grid Fault Tests Results

The complete structure of two modules can be included in this test report without tests because the following features dont change regarding to results obtained over just one model:

• Same connection system and hardware topology. - Same control algorithm. - Output power within 1/√10 and 2 times of the rated output power or the EUT or Modular inverters.
• Same Firmware Version.

The results obtained apply only to the particular sample tested that is the subject of the present test report.

• Same control algorithm. - Output power within 1/√10 and 2 times of the rated output power or the EUT or Modular inverters.
• Same Firmware Version.

The results obtained apply only to the particular sample tested that is the subject of the present test report.

The most unfavorable result values of the verifications and tests performed are contained herein. Throughout this report a point (comma) is used as the decimal separator.

The parameters of the PV Inverter models are as following:

The aim of this test is to determinate whether the PGU is able to detect a voltage dip and to ride through this undamaged. This test has been done according to point 4.6 of the standard.

All the tests of this report have been performed with a deadband of Un ± 10 %Un. There is no command for negative sequence reactive current injection in any case.

The test has been carried out using a short circuit simulator which automatically adjusts the value of the series impedances and shot circuit impedances in order to obtain the type of fault configurated for each test.

At the electric scheme below, it can be seen the connection configuration for th is test, all the faults were simulated at the AC source.

In the page below it is provided a table with the test co nditions based on the table 4-688 and 4-69 of the FGW-TG3 standard.

The signals definitions for all the diagrams shown in the report are provided below.
